ATTORNEK LOUIS H. REPPELL, OF KANSAS CITY, MISSOURI.

BRIGK-KILN.

Application filed May 1, 1908.

To all whom it may concern:

Be it known that I, LOUIS H. Barrett, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in vBrick Kilns, ofwhich the following is a specification.

My invention relates to improvements in brick-kilns; and my object is toprovide a kiln wherein the heat from the furnaces thereof may be equallydistributed, to the end that the green brick in said kiln may be burnedto a uniform degree of hardness and color, so that the value thereofwill be greatly enhanced.

The invention embraces a novel arrangement of ducts, lines, and dampersfor regulating the intensity of the heat and for distributing the sameto any point in the kiln, and in order that the invention may be fullyunderstood, reference will now be made to the accompanying drawing, inwhich:

Figure 1 represents a broken, irregular, vertical section of my improvedkiln on line 1--1 of Fig. 3. Fig. 2 is an irregular, horizontal sectionon line ll ll of Fig. 1. 3 is an irregular, vertical cross-section online IIIllI of Fig. 1.

1 designates the side wall of the kiln against which a series offurnaces 2 are built in the well-known manner. Each furnace consists ofa lire-chamber 3, a combustionchamber 4, and an ash-pit 5. The lirechamber and the ash-pit are separated by the customary grate-bars 6, towhich fuel is fed through an opening 7 in the front wall of the furnace,said opening being controlled by a door 8 and the ashes are removed fromthe ash-pit through an opening 9 controlled by a door 10. Air isadmitted to opposite sides of the lire-chamber and the combustionchamberthrough ports 11 communicating with two air-ducts 12 extendinglongitudinally through the side walls of the furnace. The supply of airmay be temporarily cut oil from either side of the furnace by pluggingthe entrance to either of the air-ducts with a loose tile or brick.

13 designates two peep-holes extending longitudinally through the sidewalls of the furnace in alinement with like holes 14 in the kiln-wall,so that the operator may look into the kiln and ascertain the conditionof the brick therein.

In order that the heat from the furnace may be equally distributedthroughout the Specification of Letters Patent.

kiln, 1 provide the latter with two flues 15, two lower hot-air ducts 16located imme diately above said fines, and two upper hotair ducts 17leading from the upper portion of the combustion-chamber. Flues 15 leadfrom the lower portion of the combustionchamber, and the walls thereofrest on the floor of the kiln, into which latter they may be extendedany desired distance. The entrances to fines 15 and ducts 16 arecontrolled by a pair of dampers 18, provided with chains 19 extending upthrough the top of the 0011i bustion-chamber and adapted to engage anyof the pins 20 projecting from the kiln-wall to support the dampers inraised positions. Dampers 18 may be lowered to completely close theentrances to flues 15 and ducts 16, or they may be arranged to partlyclose or entirely open the same, and in this manner control the escapeof the heat into the lower portion of the kiln.

21 designates a pair of hot-air ducts leading upwardly in the kiln-wallfrom ducts 17 and thence inwardly into the kiln, as shown in Fig. 1. Theflow of hot-air through ducts 21 is normally controlled by dampers 22which extend outward through the kiln-wall within easy reach of theoperator.

23 designates a pair of dampers slidably arranged in ducts 17 andprovided with handles 24 extending outwardly through the front wall ofthe combustion-chamber. Dampers 23 may be adjusted to simultaneously cutoff the flow of hot-air through ducts 17 and 21, by drawing thembackward until they close the openings at the lower ends of ducts 21, orthey may be adjusted to close ducts 17 alone by pushing them inward tothe position shown in 1, or they may be entirely withdrawn from ducts 17so that the hot-air may freely flow through the same and also throughducts 21 into the kiln.

From the above description it is apparent that I have provided means forinsuring an equal distribution of hot-air throughout the kiln and meansfor controlling the same as conditions require.

Having thus described my invention, what I claim is:

1. in combination, a brick-kiln, a furnace adjacent thereto, a hot-airduct leading from said furnace into said kiln, a hot-air ductcommunicating with the first-mentioned one extending upward in the kilnwall and thence inward into said kiln, and a damper whereby one of saidducts may be closed independently of the other or whereby they may be Idampers for independently controlling the simultaneously closed. upperand lower hot-air ducts, substantially 2. In combination, a brickkiln, afurnace as described. adjacent thereto, hot-air ducts leading from Intestimony whereof I affix my signature, 5 the upper portion of saidfurnace into said in the presence of two witnesses.

kiln, hot-air ducts communicating with the LOUIS H REPPELLfirst-mentioned ones extending upward in the kiln walls and thenceinward into said I Vitnesses: kiln, hot-air ducts leading from the loweri F. G.F1soHER, 10 portion of the furnace into the kiln, and M. COX.
